Web surveys

Created: - Updated:

Web surveys are an extension of Lumi Say's current mobile app offering, and can be used for surveys or diaries (though due to the nature of diary projects the native app is the recommended tool). Our web surveys are designed with a "mobile first" approach, but are also compatible with desktop browsers. Because of the "mobile first" approach, the visualization on desktop browsers may differ slightly from other web survey products (e.g. each question appears on a new page). At the same time, the display of a survey has been specifically thought through for desktop devices. Below, you will find examples of how our web surveys are displayed on PCs and mobiles.


Web surveys suit a number of scenarios that currently are difficult to serve with an app solution. For example: 

  • One-off surveys (launched with a web link or QR code) 
  • River sampled surveys
  • Pre-recruitment surveys (e.g. before asking panelists to download the app)
  • PC-based surveys (i.e. surveys aimed at groups of people more likely to use or take part on a PC) 
  • Surveys on devices not supported by our native apps (e.g. Windows phones, BlackBerry).

Creating a web survey

In the Lumi Say dashboard, there is no difference between scripting a survey for a mobile app, or scripting one for a web survey. Both survey types are scripted once and can be visualized as web or in-app depending on how you publish the survey, and whether you have enabled allow web display in the project properties.

Note: Due to the constraints of HTML5 technology, some Lumi Say functionality that makes use of mobile device native features is not currently supported for web surveys (e.g. Geo-triggering, video recording). For a complete list of the supported functionalities, please see below.

Launching a web survey

A web survey is launched via a web link. A web link is generated for each survey or diary that is created in the Lumi Say dashboard, and can be customized with a number of extra parameters. To launch your survey via a web link, choose use a survey link in the assign tab.

Restricting access to the link

By default, the survey web link can be accessed by both respondents whose user names are preloaded in the platform, and respondents who are created on the fly. For details, see survey link (dynamic allocation).

If particular security measures are needed, you can restrict access to the survey link to those respondents who are already preloaded in the respondent manager. In order to enable such a restriction, you will need to publish the survey to a list of respondents and make sure allow web display is enabled in the project properties.

In this way, respondents will receive the survey link and will be prompted whether:

  • They wish to download the app and take the survey
  • They wish to continue and take the survey from their browser

If you want to restrict access to the link and force respondents to take a Lumi Say web survey, please check the dl parameter in the advanced survey link (dynamic allocation) section.

Survey end target

The end target is the web page the respondent is directed to at the end of a web survey. Lumi web surveys have a pre-defined end target, which can be customized by adding this parameter to the survey tag:

<survey id="100" end_redirect="http://google.com" .. parameters>

   <item id="1"/>


List of supported functionalities

The table below summarizes the features available in our app and web surveys/diaries.

Note: surveys and diaries containing features not compatible with web surveys will not be displayed in the browser. In this situation, when the respondent clicks on the survey link, a message will be displayed to the respondent, explaining that the survey is not viewable on the web, and preventing them from continuing with the survey.
